PAVEMENT-MARKING MACHINE.

Application filed November 9, 1922. Serial No. 599,883.

To all whom it may cmwern:-

Be it known that I, JoHN OTIO BHIIEN, a citizen of the United States,and aresident of Santa Cruz, county of Santa Cruz, State of California,have invented a new and useful Pavement-Marking Machine, of which thefollowing is a specification.

The present invention relates to improve ments in painting machines andhas par ticular reference to a device of the character described thatmay be used for the purpose of marking pavements or garage floors or thelike with guide lines such as are now commonly used on busy city streetsto establish safety zones or the like. Itis proposed to provide amachine mountd on a truck that will draw a paint line when disposed inan operative position by merely being passed over the pavement on whichthe line is to be drawn. Further objects and advantages of the devicewill appear as the specification proceeds.

The preferred form of my invention is illustrated in the accompanyingdrawing in which Figure 1 shows a side elevation of my device, Figure 2a vertical section through the same, and Figure 3 a horizontal sectionthrough the same taken on line 3-3 of Figure' 2. While I have shown onlythe preferred form of the invention it should be understood that variouschanges or modfications may be made within the scope of the claimshereto attached without departing from the spirit of the invention.

My device is preferably mounted on a three wheel truck (1) having asuitable frame (2) supported on the front and rear axles (3) and (4)which latter are mounted in suitable wheels. (6). Substantially midwaybetween the two axles a transverse tube (7) is supported in the frameclosed at both ends by the caps (8). A solid casting (9) preferably ofthe shape shown in Figures 1 and 2 provided'with a central verticalpassage (11) engages the tube (7) by means of a sleeve (12) andcommunicates with the inside of the tube through the port (13). In theupper end of the passage is supported by a threaded engagement (14) theneck 50 (16) of a cylindrical receptacle (17) which is elongated in formand extends upwardly to a considerable height slanting rearwardly asshown in the drawing and closed at its, upper end by a suitable lid(18). casting is also supported as shown at (19) In the a handle (21)which extends in parallel relation tothe receptacle and is of suflicientlength to allow of the convenient manipulation of the truck.

The casting has supported therein two downwardly extending brushes (22)and (23), the former which is first in order slanting rearwardly whilethe latter which follows the path of the former occupies a substantiallyvertical position. The brush (22) extends within operative proximity ofa cook (24) communicating with the inside of the tube (7 and controlledby a valve (26) provided with a suitable handle (27) to the extreme endof which is secured a rod (28) supported in parallel relation to thehandle (21) and terminating at its top end in a hook (29) of suitableform. The mouth of the cock (24) discharges into a small paint catcher(31) which latter communicates with an internal passage (32) in thefirst paint brush adapted to deliver the paint at the root of thebristles (33). The weight of the receptacle (17) which is to be' filledwith liquid paint tends to tilt the casting rearwardly on its pivotalsupport (7) and the hook (34) supported in the front end of theframe-(2) engaging a notch (36) in the casting is used to prevent thereceptacle from tilting the casting beyond an operative position.

The brushes are arranged in such a man ner that if the receptacle isswung into a vertical position such as indicated in dotted lines inFigure Ineither of the brushes will touch the pavement surface, thefirst brush occupying at this time a horizontal position as shown inFigure 1 in dotted lines and the second brush being lifted sufiicientlyhigh to clear the pavement.

The operation of the device is very simple. After the receptacle hasbeen filled with liquid paint it is only necessary for the operator totilt the same into the operative position shown in full lines in Figure1 securing preferably the casting by means of the hook (34) engaging thenotch (36) when both brushes will sweep the pavement surface.

When advancing the machine the operator opens the cook (24) by means ofthe rod (28) and paint is allowed to flow through the paint catcher tothe root of the bristles of the first brush from where it will bedistributed over the pavement surface, the second brush following thepath of the first one serving tosmoothen the paint.

When a certain line is finished the operator tilts the receptacle intothe inoperative position shown in dotted lines in Figure 1 in which itmay be held by the hook (34) engaging a second upper notch (37 and inthis position both brushes clear the surface of the pavement. Theoperator simultaneously, of course, closes the cock (24) and is nowready to move to the next line to be drawn.

I claim:

1. A painting device for marking pavements and the like comprising atruck, a paint receptacle supported thereon, a brush associatedtherewith adapted to sweep the ground surface and means for feedingpaint from the receptacle into the brush with a second brush supportedbehind the first brush adapted to follow the same for smoothing thepaint.

2. A painting device for marking pavements and the like, comprising atruck, a casting supported thereon having a'paint receptacle mounted onthe same, a brush supported in the casting adapted to sweep the groundsurface, a valve-controlled communication between the receptacle and thebrush allowing paint to be fed into the latter and a second brushsupported in the casting adapted to follow the first brush for smoothingthe paint.

3. A painting device for marking pavements and the like comprising atruck, a casting pivotally supported thereon having a paint receptaclemounted on the same, a brush supported in the front end of the castingslanting downwardly so as to sweep the ground surface, avalve-controlled communication between the receptacle and the brushallowing paint to be fed into the latter, and a second brush supportedin the casting adapted to follow the first brush for smoothing thepaint, the positions of the brushes being such that they lose contactwith the ground surface when the casting is tilted forwardly into aninoperative position.

4. A painting device for marking pavements and the like comprising atruck, a casting pivotally mounted thereon having an elongatedreceptacle supported on the same with the receptacle slanting upwardlyand rearwardly, a handle supported on the casting in parallel relationto the receptacle, two brushes extending downwardly from -the casting soas to sweep the ground surface in successive order, a valve-controlledcommunication between the receptacle and the first brush allowing paintto be fed into the same and a hook supported in the truck adapted toengage either of the two notches in the casting for holding the brushesin an active or an inactive position.

5. A pavement marking machine comprising a truck, a receptacle pivotedthereon adapted to be swung into driving relation with the truck, meansassociated therewith for feeding paint to the pavement surface and abrush supported in fixed relation to the receptacle for engagement withthe pavement surface when the receptacle is held in driving position andclearing the said surface when the receptacle is turned into a verticalposition.

6. A pavement marking machine comprising a truck, a casting pivotallysup ported thereon having an elongated receptacle mounted thereonadapted to be swung into driving relation with the truck, meansassociated with the receptacle for feeding paint to the pavement surfaceand a brush extending downwardly from the casting for engagement withthe pavement surface when the receptacle is held in a driving positionand clearing said surface when the receptacle 'is turned into a verticalposition.

7. A pavement marking machine comprising a truck, a casting pivotallysupported thereon having a handle extending therefrom adapted to beswung into driving relation with the truck, an elongated receptaclemounted parallel to the handle having means for feeding paint to thepavement surface associated therewith, and a brush extending downwardlyfrom the casting for engagement with the pavement surface when thehandle is held in a driving position, and clearing the said surface whenthe handle is turned into a vertical position.

8. A pavement marking machine comprising a truck, a paint receptaclepivoted thereon having a brush supported in fixed relation theretoadapted to engage the pavement surface and having means associatedtherewith for delivering paint to the surface, the brush contacting thepavement surface when the receptacle is held in a rearwardly slantingposition, and clearing the said surface when the receptacle is held in avertical position.
